I was driving north on US 75 at a high rate of speed. I noticed the streaking green light appear in the NE corner of my windshield. It seemed to have come from behind me at a rapid rate of speed, and at a flat trajectory. It appeared to dip slightly, and as it corrected from the dip, it then disappeared completely, leaving no trail. The light almost had a neon quality, and the flight pattern reminded me of a swooping firefly..
